ELEGTROLYTE FOR STORAGE BATTERIES.

No Drawing.

To all whom it may concern Be it known that -I, WILLIAM GARnINER,

a citizen of the United States of-America,

and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Electrolytes for Storage Batteries, of which the following is a specification. p

My invention relates to an improved electrolyte for storage batteries, and particularly to an electrolyte in which the acid solution is held by a suitable absorbent material, whereby a solid or semi-solid electro- 1 lyte compound is obtained.

My invention will be best understood from the following description of the manner in which theelectrolyte is prepared: I first prepare a solution of sulfuric acid,

preferably one which will test about 1,300

specific gravityat 60 Fahrenheit. To this solution I add about ten per cent. of water,

and a small quantity of sodium silicate or water glass. But a small quantity of silicats is necessary," usually not over one per' cent. I then add to this silicate solution a mixture consistingof equal parts of plaster of Paris and powdered soapstone or talcum,

until I obtain a compound having a spongelike consistency. The best results are usually obtained by using about two per cent. of this mixture of plaster of Paris and powdered soapstone, although these amounts may be varied to a'certain degree without material]. afifecting the compound.

Instea ofadding the mixture of laster 0f Paris and powdered soapstone to t e silicats and acid solution, I may omit the plas- Specification of Letters Patent.

ter of Paris and merely add soapstone or talcum to the silicate acid solution.

While I have described the preferred embodlments of my invention and set forth certain specific proportions for obtaining the best results, it is to be understood that I do not wish to be limitedto the exact proportions disclosed, but. that certain changes and modifications may be made Without departing from the spirit of myin- .-ca'te, plaster of Paris, and powdered 'soapstone.

5. An electrolyte for ,storage batteries consisting of an acid solution, one per cent. of silicate, and two per cent. of powdered soapstone. i

6. An electrolyte for storage batteries consisting of an acid solution, one per cent.

of silicate, and two per cent. of a mixture ofglaster of Paris and powdered soapstone.
